Hi,
So, I've created some complex Pd patches that do what I want very nicely. I decided to write some of my creations to CD. Listening to the selections on my good CD player with excellent headphones, I heard some acoustical artifacts that I hadn't noticed when I was working in front of my computer listening through speakers. This extra "buzzing" sound is quite annoying. It's hard to imagine how my patches are making it. Does anyone have any wisdom about how to track down and fix these kind of problems? Are there any usual things you check first?
At first, I thought it might be the process of transferring the ".wav" files to a CD-R, but when I listen with headphones, I can hear it directly from my dacs (Edirol UA-25). It doesn't matter if I set the sampling rate to 96000. I thought [freeverb~] might be adding the sound, but when I bypass freeverb I still hear it. My basic sound producing algorithm is derived from the exponential waveshaping example in the documentation. Maybe there is some marginality or limitation to that approach that I don't understand?
Well, thanks for reading. Even if you don't have any ideas for me, I think it would be interesting to hear stories about how people have tracked down and fixed their own sound "bugs."
Cheers, David
